Upkeep free chains employing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot wherever lubrication is tough. It employs bushings manufactured of the sintered alloy which impregnates lubricating oil.
For the use that requires clean physical appearance, rustless kind (URN) is accessible.
Advisable utilizes
?Situations wherever lubrication is difficult or elongation of chain regularly happens Remarks for use.
?Never use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is to the use below light or medium load.Use O-ring chain whenever a big influence is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduced.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than those of standard roller chains in order to compensate for that power lowered through the utilization of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Use the tables of maximum kilowatt ratings for sintered bushing roller chains that cover reduced speed ranges.
For sintered bushing roller chains, “Low-speed selection” can not be used because the “Maximum allowable load” inside the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset hyperlinks
For sintered bushing roller chain, R connecting links are employed for DID60 or smaller sized, and C connecting links for DID80 or larger.
OJ is usually applied as offset hyperlinks. Please spot an buy the connecting links and offset back links specifying the kind for sintered bushing roller chain.
During the tables of greatest kilowatt ratings, the strength from the connecting links and offset links are taken into consideration.
Sprockets
Normal sprockets is often utilized for sintered bushing roller chains.
